Recently, many friends have consulted about the introduction of the specifications and models of bridge steel handrails, in view of this, we have sorted out the relevant content, I hope it will be helpful to you.
Bridge steel handrail guardrail is a safety facility used to protect pedestrians and vehicles on the bridge. Its specifications and models are usually determined according to the specific bridge design and use conditions, and the common ones are the following types:
1. U-shaped handrail guardrail: made of U-shaped steel, shaped like the letter U, installed on the railings on both sides of the bridge to provide protection for pedestrians and vehicles.
2.High guardrail: The guardrail material with higher height is used to increase the protection effect, which is generally used for tall bridges or highways, etc.
3.Railing with holes: The design of the hole in the railing not only ensures the protection function, but also reduces the wind resistance, which is suitable for bridges under some special conditions.
In the construction process of bridge guardrail, the following process flow is usually included:
1. Bridge pretreatment: clean up the debris and corrosion on the surface of the bridge to ensure that the foundation conditions of the construction are good.
2.Guardrail production: make guardrail materials according to specifications and models, cut, weld and surface treatment, such as anti-corrosion, spraying, etc.
3.Guardrail installation: The made guardrail materials are installed in the fixed positions on both sides of the bridge, and fixed by bolts, welding, etc., to ensure stability and firmness.
4.Guardrail Connection: Adjacent guardrail materials are joined together to form a continuous guardrail system to provide better safety protection.
5.Guardrail acceptance: Carry out the acceptance of guardrails, including appearance inspection, size inspection, weld quality inspection, etc. Ensure that the quality of the guardrail meets the requirements and can effectively provide safety protection.
In the process of guardrail construction, the following points need to be paid attention to:
1. Safety first: construction personnel must strictly abide by the safety operation procedures and use personal protective equipment that meets the standards to ensure safety during the construction process.
2.Material quality: The quality of guardrail materials is directly related to the quality and service life of construction, high-quality materials should be selected, and quality inspection should be carried out in accordance with the requirements.
3.Construction quality: the welding process should be standardized, the weld should be uniform and firm, and the verticality, horizontality and other dimensions of the guardrail should meet the design requirements.
4.Acceptance criteria: During the acceptance process, it is necessary to strictly follow the relevant standards for inspection, such as weld testing standards, impact resistance, etc., to ensure that the quality and performance of the guardrail meet the requirements.
The bridge steel handrail guardrail is manufactured and installed according to specific specifications and models, and undergoes strict process flow and acceptance to ensure that it can provide effective safety protection.
